Guide for a sliding glazing

Abstract

Guide for a sliding glazing, in particular for an automobile, the guide being intended to be fastened onto a glazing and to cooperate with a glass run seal, the guide comprising a body made of a single piece and having an elongated shape along an axis (A), the body comprising: a fastening portion extending along the axis (A) and having a face configured to be fastened onto the glazing, and a guide portion extending along said axis (A) and being cross sectional L-shaped, the guide portion comprising a wall substantially parallel to the face and a free rib substantially perpendicular to the face, the free rib including at least one non-planar lateral face.

The invention claimed is: 
     
       1. A guide for a sliding glazing, said guide being intended to be fastened onto a glazing and to cooperate with a glass run seal, said guide comprising a body made of a single piece and having an elongated shape along an axis, said body comprising:
 a fastening portion extending along said axis and having a face configured to be fastened onto the glazing, and 
 a guide portion extending along said axis and being cross sectional L-shaped, said guide portion comprising a wall substantially parallel to said face and a free rib substantially perpendicular to said face, said free rib including a first lateral face facing said fastening portion and a second lateral face opposite to said first lateral face, 
 wherein at least one of said first and second lateral faces is non-planar and includes an alternation of bumps and hollows. 
 
     
     
       2. The guide according to  claim 1 , wherein both first and second lateral faces are non-planar. 
     
     
       3. The guide according to  claim 1 , wherein at least one of said first and second lateral faces is corrugated or wave-shaped. 
     
     
       4. The guide according to  claim 1 , wherein said free rib has a substantially constant thickness along said axis. 
     
     
       5. The guide according to  claim 1 , wherein said free rib is shaped as a wave or a ripple. 
     
     
       6. The guide according to  claim 1 , wherein said free rib includes an alternation of portions having a thickness E1 and portions having a thickness E2 which is different of E1. 
     
     
       7. The guide according to  claim 6 , wherein E1 is lower than or equal to 0.85*E2 or is higher than or equal to 1.15*E2. 
     
     
       8. The guide according to  claim 1 , wherein said free rib is shaped as a pearl necklace. 
     
     
       9. The guide according to  claim 1 , wherein said wall and said free rib of said guide portion have a similar or identical length along said axis. 
     
     
       10. The guide according to  claim 1 , wherein said guide portion includes a single free rib. 
     
     
       11. The guide according to  claim 1 , wherein said wall is non-planar and/or has a non-constant thickness. 
     
     
       12. The guide according to  claim 11 , wherein said wall includes an outer face and an opposite inner face, said free rib extending from said outer face, at least one of said outer and inner faces being non-planar. 
     
     
       13. The guide according to  claim 12 , wherein at least one of said outer and inner faces includes an alternation of bumps and hollows. 
     
     
       14. A sliding glazing for an automobile, comprising a glazing and at least one guide according to  claim 1 , said at least one guide being fastened onto an inner face of said glazing. 
     
     
       15. A module for an automobile, comprising:
 a sliding glazing according to  claim 14 , 
 a trim of a door frame, said trim extending along said axis and comprising an outer face intended to be substantially aligned with an outer face of said sliding glazing, and 
 a glass run seal, said glass run seal comprising a strand which extends along said axis and which defines a recess for receiving said guide portion, said strand having an outer branch having an outer groove receiving a rim of said trim and an inner groove receiving said free rib. 
 
     
     
       16. The module according to  claim 15 , wherein said first and second lateral faces of said free rib are suitable to slide onto lateral faces of said inner groove, and said wall includes an outer face suitable to slide onto a portion of said outer branch defining said outer groove. 
     
     
       17. The module according to  claim 15 , wherein said strand of said glass run seal has a length which is lower than 150% of a guide length.
